Cold Ward Bunkers and Radar Stations

Bunker Building

The better part of half the twentieth century has been taken up by a war that never was. With two of the biggest nations rattling sabres and pointing nuclear missiles at each other (US and USSR), the Government of the UK decided that a network of Government and Regional bunkers and hardened radar stations were needed to ensure the continuity of government in the event of nuclear war, and to provide warning of incoming Russian Bombers.
The bunkers were built as a means for the Government to survive and continue to function in the aftermath of a nuclear war, the aim being effective control of the recovery period. Bunkers were built by local authorities for their localised emergency planning and Civil Defence and Utility providers of water, gas and electricity also built scores of bunkers and hardened stores all round the country to house engineers and supplies that could ensure essential infrastructure services were able to be repaired and supplied during the recovery period. Many of these bunkers were converted from suitable World War Two sites, (especially the WW2 radar stations and Anti-Aircraft Observation Rooms), but many were built from scratch at a great expense from the 1950's right up until the late 1980's to early 1990's.
The government envisaged a network of sites that all gathered information and disseminated it to other sites to be acted upon. For example the Royal Observer Corp were tasked with plotting fallout patterns and triangulating bomb detonation coordinates, which they would have fed back to group control, which would have been passed on down the line till it reached the highest level of government for action, and the RAF were tasked with operating Radar stations to ensure the security of the sky over the UK and to provide warning of incoming bombers.

This idea of 'bunker' building had begun in the Second World War to enable the government to be protected and to continue to function in the heart of London during the blitz. The plan in a conventional war was to have Central Government delegating responsibilities for Civil Defence and Rescue through the various regions of the UK, down to the local authority and finally to parish levels. During the Cold War it was realised that in a nuclear exchange this would be impossible to do as communications and infrastructure would be so wholly destroyed that society would become fragmented, especially as some areas would be more heavily damaged than others depending on their strategic importance.

Regional Bunkers

The decision was taken during the 1950's to build Regional bunkers for the local Government to manage their area after a nuclear strike. These bunkers started as the Regional War Rooms with a staff of about 45 which operated at a local level to coordinate Civil Defence corps. Mistakenly it was envisaged that even though nuclear weapons had been developed, the next war would be one of saturation bombing over a period of years. It was quickly realised however that a nuclear war would be short - maybe only a matter of days but the recovery and rebuilding period would be years. The Government decided that these 'Regional War Rooms' would not be suitable for a long drawn out recovery period after a short atomic war as they lacked the communication and scope for expansion to enable them to restore order to their much devastated region over a great period of time in isolation.

As a result of this realisation Regional Seats of Government (RSG's) were devised in the late 50's, with a much larger staff of around 300 and greater, more sophisticated communications. Due to economic crisis of the 50's plans were scaled back and no new bunkers were built but rather existing War Rooms and other suitable structures were utilised. At the same time the Regional Commissioner changed from being a local authority appointee to a central Government appointee - their responsibility became primarily to Whitehall and their role would be to assume the mantle of central Government authority should communications with London be lost. This new role gave the Regional Commissioner supreme power over the local military commanders and they could use the forces and assets at their disposal as they saw fit. All the branches of the Military and Civil defence and Utilities services were represented in the Regional Seats of Government. These RSG's were again abandoned in the mid 60's and replaced by Sub-regional Headquarters (SRHQ) to maintain the link between Central Government and Local Civil Defence Controls as it was realised that there was nothing to bridge the gap between RSG and localised civil defence controls as there had been with the War Room model. Eventually under the Thatcher government these RSG's morphed into Regional Government headquarters (RGHQ's) either in refurbished sub-regional control buildings or in entirely new purpose built bunkers. The RSG's that weren't reused were refurbished as Regional Sub Controls (R-SC's).

Essential Services

The utility companies also got in on the act in the 1980's and with 100% loans promised by the government to finance bunker building and emergency nuclear planning, many 'Essential Service' bunkers were also constructed. The government of the 1980's particularly wanted provision made for 2 litres of drinking water available for every survivor of the next nuclear war, and approached the water companies to build bunkers were the water supply could be controlled and coordinated; and in case of disruption restored. Many water companies were not keen on this as it was obvious to all that the cold war was drawing to a close by the end of the decade and they did not want to go through the sheer hard work and hassle of building a score of bunkers. Despite this a number of bunkers were built in order to meet the Governments requirements. A particularly good example is the Southern Water bunker near Chatham in Kent.
prior to this, during the 1950's several hardened warehouse type buildings were constructed to house essential maintenance and repair for GPO and the National Grid. This was to enable them to maintain the phone and electricity networks in the event of a nuclear bomb detonation. They commonly are mistaken for aircraft hangers or ammunition stores as they are of a similar design. They were built for each region of the country in countryside 'safe' areas
